The phase stabilization experiment of the four-beam combined system is performed. The phase differences between the SBS waves are stabilized within lambda/30, and the output energy flucutuation is 6.16% during 2000 laser shots (200 s).
We developed new techniques for phase control and waveform conservation of a stimulated Brillouin scattering wave. Using these techniques, a laser fusion driver using beam combination, with which the output energy can be unlimitedly scaled up with high repetition rate over 10 Hz, can be achieved.
After the laser was invented in 1960, a phase conjugation mirror has been respected to be the most fantastic one for the laser resonator composition because it can compensate any distortions of the laser beams occurred by the many inhomogenuities of the laser media and optical components. Among the many phase conjugation configurations, the stimulated Brillouin scattering phase conjugation mirror...
